Topic: Davinci Jr and Mini Regional Tag Swap

This thread can be used to connect two people within the same region for a tag swap. Post your needs and the region of the world you are in. If you can help someone out by swapping a tag you can no longer use contact them via PM and work out the details.

As you send your tag to another user please include the UID (Tag Serial Number) along with the Password and Color to make it easier for the person receiving your tag. Also, before returning the replacement tag. It might be a good idea to ask the recipient what color they would like and what length they would like the new tag set to. To much information is better than not enough.

At this point in time this is just experimental as no one has documented if the tag from one printer will work on another or not.

I am currently in the process of doing a tag swap myself. I will post results here.

If anyone is interested. There is a shipping container at the following location to help in keeping the tag secure:

Re: Davinci Jr and Mini Regional Tag Swap

Good idea. I'm located in Sweden. So far the only empty tag I have is a clear blue 100m tag that came with my printer but I have 8 different rolls of filament in different colors and they will not last forever, so if this works I'm all in for swapping tags. smile

Re: Davinci Jr and Mini Regional Tag Swap

This will be a good solution until it can be figured out how to either create new tags from blank NFC cards or else edit the XYZ Printing program to not even look at the tag data. I live in the US and running a Da Vinci minimaker (not the wireless version).  I am running software version 2.1.15.1, printer firmware version 1.0.0 and the cartridge I am working with is a 100 meter yellow demo roll that came with the printer. It is not locked but now that I have made changes I get the “cartridge cannot be recognized” error.

Re: Davinci Jr and Mini Regional Tag Swap

I would contribute but i'm not really sure what the theory behind this is. Why would swapping tags help?

In theory, if the printer stores tag information. As long as the tag is not locked. You should be able to swap tags so the printer see a tag it does not recognize. So when you do a tag swap. It's just like buying a new spool of filament.

I thought the printer wrote the values back to the chip?

Re: Davinci Jr and Mini Regional Tag Swap

Yes, but the tag can be modified if you have the password. I have been using one tag for a year now. I have two new ones still in their original containers. This is the whole purpose of hacking the tags is to reuse them. Now what we have been seeing is for some reason the Mini's have be able to either store information about the tags or have been updating them to make them unusable. So until we can figure out which it is, by swapping them would be like having a new chip. I think there is a second chip headed my way. Again, I will post the results here as soon as I can. I hope the other person doing the swap will do the same.

Sounds like a good idea. Located in Sweden.
I'm using a mini btw, haven't gotten around
to trying a modified chip yet but I will soon.

Edit: mention of mini.

Re: Davinci Jr and Mini Regional Tag Swap

Hi everybody.

I´m owner of da Vinci Mini w, I bought it in Slovakia, maybe it was delivered from Czech Republic to Slovakia shop with clear blue 100m tag that came with my printer. I tryed to send NFC data to this forum.

    Page : Data
    [00] : 0494968E
    [01] : 8A3E4D80
    [02] : 79480000
    [03] : E1101200
    [04] : 0103A00C
    [05] : 340300FE
    [06] : 00000000
    [07] : 00000000

And recieved the password: CD 27 5E A6

But this password is not working. For now i have idea. I would like to buy another extra filament original for da Vinci Junior and try to hack with android app. Did somebody try this or have any other idea?

Thanks a lot.

Please read this thread: http://www.soliforum.com/topic/15815/xy … w-hacking/

It has been tried and currently it does not work, the purpose for this thread is to swap used NFC chips with others to try if it is possible to modify and use a chip that has not previously been used on one specific printer.

And if the password you received did not work, try a different android device. None of the passwords worked for me with an old (android 4.4) Samsung phone. Then I tried my Nexus 9 and the same passwords worked perfectly. I've so far got passwords for all my 9 filament spools and all of them worked.

However, this is not the thread for this discussion. This thread is for swapping NFC chips with other forum users IF it turns out that it works modifying a chip that has not before been used on a specific printer.

Edit: mention of mini.

Since we are both in Sweden, let me know when you've emptied a roll and want to swap. I have one empty chip (with password) from the 100m clear blue roll that came with my printer. I've been experimenting with it but I've got a photo of the contents of all the pages when it was empty and I hade not yet modified anything. I will restore all the values to that state before swapping.

Why restore it to the original 100m?
We can easily set the length to 300m so it can be used for longer - on a different printer..

Cgrillo could you please tell me the data for 300m? I cant find the checksums for this value. (Page 21 to 23)

I'll restore it to the state it was when it was empty and before I started to modify it. I assume anyone who swap chips with me wants to do any modifications themselves depending on how they plan to use the chip.

Re: Davinci Jr and Mini Regional Tag Swap

Here is an update for Tag Swapping.

I just received my first tag in the mail. It was configured for 200M so I changed it to 300M then placed it in my printer. When I check the Tag status it showed as a good tag with 300M of filament on it. So I can say the tags are not being locked by XYZ so it must be storing the usage on the printer. If the results on the Mini's is the same. This looks to be a solution until someone is able to crack the encryption.

When I try my modified NFC chip it always looks OK until I try to print something. Did you try printing?

Also, when you say you change it to 300m, what values did you use for page 21-23? I've tried to find this information in the forums but so far I've failed.
